Tanya,
Hey there! How is the sleeping thing going? I was just going through some old posts and I wanted to tell you that you are NOT ALONE! I read through all of the responses and there have been a lot of great tips offered (I'm taking notes for the next baby!)
Ben was not such a great sleeper in the beginning. We thought he hated being swaddled, but knowing what I know now, I wished we had pushed it a little more. Have you read the book "Happiest Baby on the Block"? By Harvey Karp? It gives a lot of advice on chronically crabby, crying babies and how to comfort them into a deep sleep. We are buying the book along with a swaddling blanket before we even get home from the hospital this time!
Also, I noticed you said you fed Emily until she's content and
then changed her. We started doing that with Ben and a friend told me to try changing him first and then feeding him. If he was too hungry, I would nurse a little bit, change him (which woke him up again and thus he would eat more) and then nursed some more. He slept much better after that. Think about it. What if you were nice and full from a huge Thanksgiving dinner and drifted off into a cozy deep sleep and then BAM you're naked and cold! So much for the nice cozy sleep!

Just a thought! Good luck and let us know how things are going!
